<a href="https://youtu.be/pJiirfyJwcA">Playwright v1.35 updates</a>

### Highlights

* UI mode is now available in VSCode Playwright extension via a new "Show trace viewer" button:

  ![Playwright UI Mode](https://github.com/microsoft/playwright/assets/746130/13094128-259b-477a-8bbb-c1181178e8a2)

* UI mode and trace viewer mark network requests handled with [`page.route()`](https://playwright.dev/docs/api/class-page#page-route) and [`browserContext.route()`](https://playwright.dev/docs/api/class-browsercontext#browser-context-route) handlers, as well as those issued via the [API testing](https://playwright.dev/docs/api-testing):

  ![Trace Viewer](https://github.com/microsoft/playwright/assets/746130/0df2d4b6-faa3-465c-aff3-c435b430bfe1)

* New option `maskColor` for methods [`page.screenshot()`](https://playwright.dev/docs/api/class-page#page-screenshot), [`locator.screenshot()`](https://playwright.dev/docs/api/class-locator#locator-screenshot), [`expect(page).toHaveScreenshot()`](https://playwright.dev/docs/api/class-pageassertions#page-assertions-to-have-screenshot-1) and [`expect(locator).toHaveScreenshot()`](https://playwright.dev/docs/api/class-locatorassertions#locator-assertions-to-have-screenshot-1) to change default masking color:
  ```js
  await page.goto('https://playwright.dev');
  await expect(page).toHaveScreenshot({
    mask: [page.locator('img')],
    maskColor: '#00FF00', // green
  });
  ```

* New `uninstall` CLI command to uninstall browser binaries:
  ```bash
  $ npx playwright uninstall # remove browsers installed by this installation
  $ npx playwright uninstall --all # remove all ever-install Playwright browsers
  ```

* Both UI mode and trace viewer now could be opened in a browser tab:
  ```bash
  $ npx playwright test --ui-port 0 # open UI mode in a tab on a random port
  $ npx playwright show-trace --port 0 # open trace viewer in tab on a random port
  ```

### ⚠️ Breaking changes

* `playwright-core` binary got renamed from `playwright` to `playwright-core`. So if you use `playwright-core` CLI, make sure to update the name:
  ```bash
  $ npx playwright-core install # the new way to install browsers when using playwright-core
  ```

  This change **does not** affect `@playwright/test` and `playwright` package users.
